I would like too see this code. /me thinks you can use libiberty and
the introspector or gcc_xml for this.

like the gnu libjava

yes, let us see the basic axioms, we can build this in a standard
process.
at this point, I would like to know why cannot you use the internal
call system? that has a binding generator as well, no?

you can grab pointers to virtual function entries,
and given an object and a vf pointer call the object.
please send me more info,
I just might be able to help.
